When running src/build_packages.m in a freshly installed mxe-cross built

In virtually none of my MXE cross-builds I see a libblas.dll, yet I haven't
encountered any problems in the last year (and I sometimes do heavy
computations). Intruiging. AFAICT I have MXE setup with OpenBLAS.
Copying over libblas.dll from octave-3.9.0+ (from early Dec last year) into
/bin gets me exactly the same errors during installation of the tsa package.

Some of my Octave settings:

>> octave_config_info("features").BLAS
ans = 0
>> octave_config_info("BLAS_LIBS")
ans = -lopenblas


So perhaps a more robust numerical library detection is needed in the
mkoctfile call in the tsa package?
